Fuzzy sets 79
Consider a distillation process to separate components of a mixture. Let hot = 
be a fuzzy set on X where x ∈ X i the temperature measured in 0C, 
and 
, where y ∈ Y is the percentage of separation.
Let p1 be the proposition ‘IF temperature is hot, THEN separation is good, ELSE separation is average’.
Note that: If P and Q else R is translated as (P ⇒ Q) ∧ (∼P ⇒ R)
